Two survivors of coronavirus who met in hospital and have since become friends, have decided to take part in a trial at a blood donation clinic in Gloucester to help fight the virus.
Dave Lewins and Jules Annan met in hospital in Cheltenham but the trial they are taking part in is part of a nationwide effort.
The aim is to investigate if the antibodies in the blood plasma of those who have had the virus, which can give them future immunity, can help others who are seriously ill.
It was really important that I came down with Jules - we met on the ward, we've had daily contact ever since and we've discussed a lot about our family life and the associated anxieties.
He was the only person I saw in the whole time I was there who came from ICU backwards, everyone else was moved from HDU to ITU, it was just great to see someone recovering from it.
Watch below how the trial works
There are strict medical guidelines on who can donate their blood as part of the trial.
Among these guidelines those participating are checked to see if they have had any recent symptoms, before they fill out a more detailed questionnaire.
Once they have satisfied the necessary criteria, they then go onto take part in the trial.
But Jules and Dave have both been rejected due to existing conditions.
My breathing isn't good enough so I can't do it. I am very upset about it but I understand the reasons why [I have been rejected].
It transpired that the cancer that I had 20 years ago, means I am banned now for life from giving blood, as there is a small possibility it could be passed on.
Other people who have had the virus are being encouraged to come forward, as with the trials being nationwide, the majority of blood donor centres are helping to see it through.
